This invention relates .to v -trusses designed and adapted for use concrete floors tolrein-w force, strengthen, and support the concrete floor permitting the concrete to enter and fill the space between the downwardly converging websof the truss; to provide a light-weight sheet metal truss including downwardly extended webs united by a top portion having integral therewith tongues extending downwardly between the webs and holding them in proper spaced relationship, and provided with openings into and through which the concrete may pass toform integral connection with the concrete on opposite sides of said tongues; to provide at the lower chord of the truss an appropriately formed bar located between the websof the truss andflush with the bottom edges thereof to add additional strength thereto when the truss is in tension in the floor; and to provide a light-weight sheet metal 'truss having downwardly extended webs which may be spaced apart by any appropriate means and attached along their upper edges or not, as desired. 7

Another object of the invention is to' provide a truss of the character mentioned having flanges in connection with the lower edges of the :Webs and the strengthening bar to support the spanning member or void-filler upon which the concrete is poured and which supports-the concrete until the concrete hardens, and which thereafter remains in attached engagement with the concrete.

Other objects of the invention will be apparent from the following description, reference ,being made to the annexed drawings, in which-f.

The truss shown in Figs. 1 toe; inclusive, is made of light-weight she'et steel bent to form a pair of spaced webs I and 2 integrally united at their upper edges by a top portion 3. Series of openings 4, 5 and 5 are formed through each web by stamping or cutting out portions of the webs to permit'the concrete to enter between the two Webs of the truss. The top portion 3 is cut or stamped to. form, a series of tongues 'I which are bent downwardly between the webs I; and 2 andlform braces or spacers therefor holding the truss webs I and 2 in approximatelyuniform spaced relationship throughout their length. Each of the'tongues I is also stamped or cut to form an opening 8 in the upper and wider portion thereof'through which the concrete may pass to opposite sides of the tongue to form integral connection with the mass of concrete at each side thereof.

. In this form of the invention, the webs I and I 2 converge downwardly and the tongues 'I are of tapered shape conforming to the desired space between the webs I and 2. 'When the tongues In this form of the invention, an appropriate- 7 1y shaped bar"! is weldedorotherwisesecured' between'the webs I and 2 of the truss and flush with the bottom edges thereof to provide additional strength therefor when -thetr'uss is under tension in the floor. A flange II attached to the bar In extends beyond the'sides of thewebs I and 2 and consitutes a support for thespanning member or void-filler I2 upon which the con-. crete is poured and which supports the concrete until the concrete hardens, and thereafter remains in attached engagement with the concrete, afiording a finished under-surface for the floor.

Figs. 5 to 8 illustrate a modified form of the invention. ,This truss is .also made of lightweight sheet steel which is bent to form a pair of spaced Webs I3v and I4 and a top portion I'5 integrally connectedvwith the upper edges of the webs. Series of openings I6, I! and I8 are stamped or cut into the webs to permit concrete to enter between the two webs of the truss and form a mass of concrete within the truss integrally united with the concrete between the respective trusses. The top portion I is cut or stamped to form a series of tongues I9 which are extended downwardly between the webs I3 and I4 to form braces or spacers for the webs, holding them in approximately uniform spaced relationship throughout their length. These tongues are formed with openings in their upper portions through which the concrete may pass to opposite sides of the tongues and form integral connection with the masses of concrete at the sides thereof. When the tongues [9 are bent downwardly, openings 2| are; formed through the top portions l5 through which 0011-! crete may be poured if desired or required. The webs l3 and I4 converge downwardly and the tongues (9 are. of tapered. shape, conforming to the desired space between said webs.

In this form of the invention, a T-bar is used instead of the bar l0. and the flange member H. The stem 22 of the 'T-bar which is welded: to said webs is extended upwardly between the lower. margins of the web's t3 and M, andthehead 23 of said bar provides flanges to support. a spanning member or void-filler 24 upon.- which the concrete is poured and which supports the concrete until the concrete hardens, and thereafter. remains in attached engagement with the con-- crete to provide a finished under-surface for the floor.

In both forms of the invention, the concrete 25 is shown filling the space between trusses and also filling the trusses between the webs thereof. In Fig. 4', the tongues 1 cross the openings 6 and, in- Fig. 7, the tongues f9 cross the openings I8. This assures that the concrete at opposite sides of the tongues. within the trusses wilI be integrally united and also that the concrete within the trusses and at opposite sides of the tongueswill be integrally united with the masses of concrete at the sides of the trusses. The remaining series of openings in the truss webs assure that the spaces between. the webs of the trusses will be filled with concrete and integrally united with the exterior masses of concrete.

From the foregoing, it is apparent that this invention attains all of its intended objects and purposes e-fficientl-y, economically and satisfactorily. The trusses are of light weight; The webs may be formed otherwise than in V-shape when desired, and the bars l0 and supporting flange members H may be of diiierent shapes, as may the T-bars shown in Fig. 8.

Il contemplate other variations in the form and construction of these improved trusses, anddo not restrict myself otherwise than as defined by the appended claims.
